A simple standardised protocol for making monoclonal antibodies against a range of human bacteria and viruses is described. The protocol was designed to reduce the number of steps to a minimum. A one step footpad immunisation was followed by the fusion schedule 10-15 days later. A vital step in the technique was the use of the immunised mouse's spleen to provide a feeder layer post fusion. This simplified the protocol and more importantly greatly accelerated the growth of the hybridomas produced. Immunisation, fusion and clonal expansion of specific antibody secreting hybridomas was complete within 5 weeks. The percentage of hybridomas secreting specific antibody ranged from 6% to 28%, the majority of which were of the IgG isotypes. The method was economical in the use of tissue culture medium and simple to perform.
